Given numbers are 337,740,889,420
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 337,740,889,420 is 665096460.
Find LCM of 337,740,889,420 with Prime Factorization
| 2 | 337, 740, 889, 420 |
| 2 | 337, 370, 889, 210 |
| 5 | 337, 185, 889, 105 |
| 7 | 337, 37, 889, 21 |
| 337, 37, 127, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 7 x 337 x 37 x 127 x 3 = 665096460
Therefore, the lowest common multiple of 337,740,889,420 is 665096460.
LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
Firstly, we have to find the product of all the numbers.
337 x 740 x 889 x 420 = 93113504400
Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.
337 : 1, 337
740 : 1, 2, 4, 5, 10, 20, 37, 74, 148, 185, 370, 740
889 : 1, 7, 127, 889
420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 337,740,889,420, is 1.
Now, the common factors can be found like this.
337:337
740:2x 2x 5x 37
889:7x 127
420:2x 2x 3x 5x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 5x 7 = 140
Therefore, the value for common factors is 140.
Now that we have all the elements of the formula, we can plug them in to calculate the LCM.
LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
LCM = 93113504400/(1x140)
LCM = 93113504400/140
LCM = 665096460
Thus, we can understand that the LCM of 337,740,889,420 is 665096460.
